Patent

CA 2702708

A household liquid dispenser has a spout fitment with discontinuous beads or screw threads which define axial channels to interface with a pump inlet in a lock and key arrangement so as to maintain consistent quality of liquids dispensed by preventing the substitution of product refills of uncertain quality. Refills may be readily manufactured and at low cost. Mechanical and motorized dispensers may be used with the inventive spout fitment.

La présente invention concerne un distributeur de liquide ménager présentant un bec verseur pourvu de bourrelets discontinus ou d'un filetage cylindrique qui définissent des canaux axiaux formant interface avec une entrée de pompe dans une configuration de clé et serrure de façon à maintenir constante la qualité des liquides distribués en empêchant qu'ils soient remplacés par des recharges de produits de qualité incertaine. Les recharges sont faciles à fabriquer et à faible coût. Des distributeurs mécaniques et motorisés peuvent être utilisés avec le bec verseur de la présente invention.
